(INDIANPOLIS) - Republican Congressman Mike Pence submitted 13 thousand signatures from supporters Monday as he tries to get his name on the ballot for the Indiana governor's race.

Meanwhile Democratic candidate John Gregg is expected to submit his list of signatures on Thursday.

Statewide candidates have to collect signatures from 500 registered voters in each of the state's nine congressional districts.

Jim Wallace is Pence's challenger in the Republican primary.

Pence far outpaces his competition in campaign funds at over $5 million, according to Eyewitness News partners at The Indianapolis Star. The Star reports Wallace has raised $1 million and Gregg has $1.7 million in campaign funds. Rupert Boneham, Survivor star, is running for governor as a Libertarian.
